Bfe it known that I, JOSEPH EUGENEMAM BRIEIST, en-Uineer, e resident atvfoe Perret, in the Republic of France, heverevented new and usefulImprovements in or Reating to Cerburetfers, which im rove ments are uyset 'o'rtlh in the foi @wavingV specieation.

This inventofl relates to a carbm'eber, oneY of the characteristic'features ofA Waieh eet it is possible to' regulate simutaneously theadnssion of Spirit and of air the of which cakes place in fa cham ersommeictng with ihe engine under the same condi-Y tiee onder which takesplace the admission of spirit and .air into the alrv params.

In order to make the felowzng description as dear es possible, acerburetereecording to tas invention is illustrated Vin theaccompadrawvings. v

Without departing from the s irit 'of this invention the carbureterdescri ed can be subjected to various modifications.

In Fi 4 I have shown a modifica on in which t eucarbureter isautomaticall `co`n trolled by the suction of the motor instead of by thegovernor, as in the previous construction. To thisy end the suction-tubeg is connected by a passage g with a chamber fu, formed in thecarbureter above the art t. The position of this part' b is control ed'automatically vby the suction of the motor, and the arrangement of agovernor is thus dispensed with. In. order, however, to be able tochange instantaneously 'the movement of the en ine, I have arran ed alever-arm u; which 1s pivoted at one en in the Walls of thecasing'fuyand which with its other extremity lu. rests on the top of thepart b. By turning the lever u downward the part u causes the `returnmovement of the piston or part b. Independentlyr of thel above theconstruction'of the carbureter can be modifiedso as to enable eitherpetrol or hydrocarbon vapors or water-gas to be used.` Fig. 5 shows, forinstance, a carbureter workin by means of liquid petrol. The liquid fueis admitted at 1 and flows down a central pipe 2. The admission of thepetrol Ainto the said pipe is regulated by means of a flattened rod inthe same. way as the admission of, spirit in the receding construction.On coming out From the said pipe 2 the liquid petrol arrives into achamber 3, arran ed in the exhaustbox 4 of the engine, and nally assesinto a tube 6, where it is va orized un er the influence ofthe suction othe en ine produced at `g. The receptacle 3 is. arranged in an outercasing 5, there `being an annular space t formed between the walls ofthe two casings 3 and 5.` The space 7 is in'connection with the pipe 6,that traverses longitudinally the exhaust-box 4. The extremities of thepipe l6 are closed to the outside. The suction of the motoristransmitted through the passage which, as -with the carbureterpresented 1n ig. 4, is in connection b a p sage ,gf 'with the chamber 'uformed in t e car ureter above the piece b. The'upward movement of thepiece?) causes the rising of the'liquid vaporized by the regained heatof the explosion gases which envelop the chamber 3 Iand the pipe 6.' Thevapors rise through the annular ace-7, formed between thee amber 3 and tle casing 5, then thrjo h the a. ular 4space `8 andthe passages 9 an:arrive into the part `10, .where they as intimately. aspossible withthe air, which enters into the apparatus through the openin 11. Finally,the combustible mixture, t e quantity of which is controlled by thedisplacement of the part b, enters the motory through the passage g.

For utilizin water-fas the. construction is as shown in ig. 6. ft is thesame arrangement as in Fig. 1 except that the rod-forming plug is muchlarger and becomes, in reality, a conical part 13, with two flattenedsides. Water-gas rises through the conduit 12 and becomes mixed with theair and then goes to the engine through the conduit What l claim as myinvention, and Idlesire to secure bv Letters Patent, is

1. A carbureter in which the admission of spirit and air issimultaneously controlled, comprising a stationary cylindrical casing,-a mixing-chamber capable of moving u and down in said Astationarycasing, the mlxingchamber having a truncated conical portion, a rodfixed in said mixing-chamber, said rod bein cylindrical at its lower endand gradually attened toward its upper end and adapted to control theadmission of the spirit into the mixing-chamber, a stationary conicalpart forming a passa e between its cone and the truncated conicaportionof themixingchamber,` said passage serving for the admission of air andbein controlled by the vertical movement of tie mixing-chamber thewallsof the mixinU-chamber having holes at its upper end for the passageof the mixture, substantially and for the pur ose as s ecied. 2. 'Thecarbureter in whic the a mission of spirit and air is simultaneouslycontrolled, comprisinar a stationary cylindrical casing, the wall o?port and ports leading to the atmosphere, a mixin -chamber provlded witha truncated conica portion capable of i'nving u down in said casing,means actuated y the movement of the mlxing-chamberto regulate the flowof the fluids according to the positionof the mixing-chamber within thesaid cylindrical casing, the above-mentioned port and conical portionbeing so situated that the truncated conical portion cuts off thecommunication of the mixin -chamber with the suction-port and establis.-es communication between the engine and' the atmosphere before theadmission of air and spirit is completely stopped, substantially as andfor the purpose specified. f

3. The carbureter in which the admission .of spirit and air issimultaneou'sl \controlled, comprising a stationary cylin rical casinprovided Withfa suction-port in'the Wa thereof., Aa mixing-chambercapable of movingnp'and down in the said cylindrical casing,- a Achamberformed above the' mixin chamber and adapted to communicatewit the motorthrough the above-mentioned suction-port, the movement of themixing-chamber being effected automatically by the sucwhich is providedwith a suction-l and IOO

iro

tionaction ofthe motor, means actuated by the movement of themixing-chamber io regof Spirit end air is simultaneously controlled,

comprising a, stationary casing provided with a. suction-.port in thewall thereof, a, mixingchamber 'capable of movin up and down 1n the s'adcasing, e chamber ormed above the mixing-chamber and adapted tocommunicete with the motor through the above-mentioned suction-port, themovement of the mixing-chamber being effected eutomatioaiy by thesuction action of the motor, a. central 'o ube connected with thefluid-supply, s. rod fixed at mie end in the mxin -chamber and engaginget 'its other end in said central tube to eontrol the ow of the fluidthrough the letter before the fluid is vaporized, means to allow thevaporization of the fluid and means through which the vaporized fluid isconve edl into the mbdng-ohember', substantia ly as and for the purosespecified.
